Intermolecular Transglycosylation of Cyclodextrin Glycosyltansferase

open access: yesJournal of the Japanese Society of Starch Science, 1979
The acceptor specificity in the intermolecular transglycosylation of cyclodextrin glycosyltransferase (CGT-ase) was investigated using 18 kinds of monosaccharides and their derivatives. It is concluded on the basis of the experimental results that the requirement for an acceptor of the intermolecular transfer reaction catalyzed by CGT-ase is the ...

Introducing transglycosylation activity in a liquefying α‐amylase [PDF]

open access: yesFEBS Letters, 1999
By mutating Ala‐289 by Phe or Tyr in the Bacillus stearothermophilus α‐amylase, we induced this enzyme to perform alcoholytic reactions, a function not present in the wild‐type enzyme. This residue was selected from homology analysis with neopullulanase, where the residue has been implicated in the control of transglycosylation [Kuriki et al. (1996) J.
